$339 with GPS pod, Polarusa.com
Standout: Ultra-light, compact, comfortable.
Weakness: Missing some functions and compatibility with non-Polar accessories.
Running is noticeably more comfortable with the Polar RCX3 because of its sleek design and remote GPS pod. It offers a wide array of features, especially when paired with the GPS sensor, although it is missing altitude, navigation and power-display functions. While the numbers can be tough to see on the smaller screen during training, helpful icons tell what data you’re looking at.
Rock it: For something fully functional when you need it, sleek and slim when you don’t.
